Embodiment Construction

[0044] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0045] see Figure 3-Figure 11 , a kind of prefabricated sandwich thermal insulation laminated wallboard, comprising inner and outer layer prefabricated wallboards and an insulation layer 2 between them, and an insulation connector; The planar grid is poured as a skeleton; the insulation connectors are pre-embedded through the inner and outer prefabricated wall panels and the insulation layer 2; the insulation layer 2 is a foam insulation material, poured in the inner and outer layers between prefabricated wall panels.

[0046] The thermal insulation layer 2 is any one of foam thermal insulation materials such as polyurethane, phenolic, foamed cement, foamed glass, and polystyrene resin.

[0047] The thickness of the thermal insulation layer 2 is 30-200mm.

[0048] see Figure 4 , the heat preservation connector is made of stainless steel, ...

Abstract

The invention relates to a prefabricated sandwich thermal-insulation laminated wallboard. The wallboard is characterized by comprising an inner prefabricated wallboard, an outer prefabricated wallboard, a thermal-insulation layer (2) located between the inner prefabricated wallboard and the outer prefabricated wallboard, and a thermal-insulation connecting piece, wherein the inner prefabricated wallboard and the outer prefabricated wallboard are poured with longitudinal and transverse tensioned bar plane frames as skeletons; the thermal-insulation connecting piece passes through the inner prefabricated wallboard, the outer prefabricated wallboard and the thermal-insulation layer (2) in an embedded way; and the thermal-insulation layer (2) is a foamed thermal-insulation material and is poured between the inner prefabricated wallboard and the outer prefabricated wallboard. According to the invention, the thermal-insulation material overcomes the shortcomings of great needs of labor and low automation degree of the traditional prefabricated sandwich thermal-insulation wallboards through one-shot injection in a factory and adequate filling and compacting of a cavity in virtue of physical and chemical changes of the material; meanwhile, the thermal-insulation material and the contact surface of the inner and outer prefabricated wallboards are effectively bonded together, so rain water is prevented from intruding through gaps produced by stripping of the inner and outer prefabricated wallboards and is thus prevented from influencing the thermal insulation effect of the thermal insulation layer.

Description

technical field [0001] The invention relates to a prefabricated sandwich thermal insulation laminated wallboard and a manufacturing method thereof, belonging to the technical field of prefabricated sandwich thermal insulation laminated wallboard production. Background technique [0002] With the rapid development of my country's construction industry and the improvement of awareness of green energy conservation and environmental protection, the modernization of the construction industry has developed rapidly, and the modernization of the construction industry is the only way to improve the overall level of my country's construction industry.
